  • Patent number: 4927751
    Abstract: Exoenzymes, such as proteases, xylanases and amylases, are obtained continuously by cultivation of exoenzyme-producing microorganisms in one step in a fermenter which is operated with continuous flow and in which a deficiency state corresponding to maximal enzyme productivity is effected. Optical density of the culture (as a measure of the biomass density) and exoenzyme concentration in culture can be monitored to control the timing and extent of the deficiency state. It is particularly advantageous to impose an oxygen limitation and to maintain the deficiency state continuously by exerting an effect on the oxygen input.
